Question
Which of the following statements is FALSE?Question 15Select one:a.Cutting a DNA fragment with EcoRI can produce blunt ends that can be joined with DNA ligase b.The EcoRI restriction enzyme will cut a DNA molecule wherever the sequence GAATTC occursc.Cutting a DNA molecule with EcoRI can produce sticky ends that can be joined with DNA ligased.Only compatible ends can be joined by DNA ligase
Solution
The false statement is:
a. Cutting a DNA fragment with EcoRI can produce blunt ends that can be joined with DNA ligase
Explanation: EcoRI is a restriction enzyme that cuts DNA at specific sites, producing "sticky ends," not blunt ends. These sticky ends can then be joined with DNA ligase. Therefore, the statement is false because EcoRI does not produce blunt ends.
